To-all whom it may concerm j Be 'it knownrthat vve,uA 'rHuR E. BLomm and JAcon J. LINK, a' citizengof the United States and a a subj ect of the Emperor of Russia, respectively,

borough of Manhattan, city, county, and

State of New York; have invented I certain Q new and usefullmprovements in Clasps, of

which the following is a-description.

Our inventionrelates to clasps andis a 'rant ned. to cover infants in their cribs. It also owever 5 described an improvedcjlasp, which we de-.

edges of the blanket or top covering linithe saidfimprovementsp in bed coverings, but which as stated, may also advantageously be used in'other connections.

This clasp comprisesthe'subject matter of j the present applicatiomi and lourobject is to n Other objects of our provide an; lmproved device of this cha'raca ter, adapted foJ securingpcoverings, garments or the like, which will" give an absolutely secure grip, will be tightened in ac cordance with the pull of thegarment or material secured thereby, upon the same, will not tear the fabric to which it isclasped, and will readily secure materials of dilferent thicknesses. a y f invention comprise the provisions of parts and combinations of elements more fully described hereinafter, andparticularly pointed out in the appended claims. v

, Attention is hereby directedto the accompanying drawings, vforming part of this specification, in i whichv Figure 1 represents a longitudinal section of one form of our improved clasp; Fig. 2 is a cross sectiontaken" on line 2-2 of Fig.

- 1, and Fig. 3'is a topplan view of the clasp shown in Fig. 1. a j

Referring to the drawings, the clasp is provided with a metallic loop 1, which is secured to the smaller end of a wedge shaped member 2 preferably formed of pressed metal.

through which a pull will be transmitted to the clasp when the latter is in gripping engagement with'the object to be secured, may be attached to the loop 1. The clamping jaws 4; and 5 in the preferred form of clasp and residents of the A strap or other connection, 3,

are pivotally mounted upon the pin 6 surrounding which is a spring such as the spiral spring 7 illustrated, and theftwo ends of which press the jaws l: and5 into open position. The lower jawfpreferably carries a pad Sof rubber or other similar "material between: which and the end ofthe jaw t the material toqbe clasped'is pressed, Thejaws 4: and 5 are mounted, as shownin the drawings, to slidefuporr one face ofthe wedge shaped member 2, thetail end of jaw 4 preferably being provided with aportion 9 bent substantially at' right angles to'the jaw and bearing uponthe surface of the wedge, this extension 9, if desired, having lugs 10 bearing on the-twosides of the wedgemember. Theuppe'r' jawe has an extension or stirrup 11 extending downwardly from its two sides and extending around-the bottom of wedge member 2, where its two,.- ends may be secured together, to form'a complete loop between which and the lower surface of the lower jaw ithe wedgemember 2isadapted to reciprocate. The length of the sides of the stirrup is so chosen in relation to the thickness of the wedge member 2 that the aws of the clasp are in open osition, when PatentedSept. 22, 1914'.

$T E$ KTO 1 the stirrup llis at the sma-l erend of the wedge, and the jaws are gradually closed by the movement-0f the wedge through the stirrup so that when the stirrup has reached such a position that the clamping ends of the jaws are directly over the large end of the wedge member 2, the jaws will be entirely closed.

It should be noted that wedge member 2 constitutes the operative member of the clasp, the strap 3 or'other supporting connection through which a pull may be 11nparted to the clasp, being connected to the small end of the wedge so that the greater the pull upon the small end of the wedge, the more firmly will the jaws grip the material held thereby. That isto say, when the clasp is in operation, a constant pull may be transmitted to the device through the supporting connection 3 which may be of elastic webbing or the like, which will cause the jaws to grip the material held thereby more tightly, and similarly the pull of the material held by the jaws, or the weight thereof, will cause the jaws to grip the same more tightly, the greater the pull, since the upper end of the wedge is held orsupported as stated. It also should be understood that when the are in closed position they are directly over the large metal bent into U shape in cross section as shown in Fig. 2

It should be understood that while We have particularly described for purpose of illustration the preferred form of our invention, the invention is not limited thereto but is as broad as is indicated by the following claims 1 Having describedour invention what we claim as newand desire to protect by Letters Patent is v l. A clasp comprising a wedge-shaped operating member having means for connecting a supporting strap thereto at the smaller end thereof, a pair of grippingjaws hinged together mounted toslide upon one exterior face of said member with the operative ends of said jaws directed toward the larger end of said member, the upper of said jaws'having a stirrup extending around the lower jaw and said member, forslidably'coacting with the latter to position said jaws and close thesame when theymove toward the larger end of'said wedge member, the said .mem-

her and jaws being so arranged and proportionedthat the operative ends of said jaws,

when in closed position are directly above the largeend of said wedge member, substantially as described.

2. Aelass comprising a pair of grippingjaws hinged together at one end, one of said awsbeing provided with a stirrup directed transversely to the face of said jaw,and a wedge-shaped operating member slidably mounted within said stirrup to reciprocate between the same and the exterior surface of one of saidjaws, longitudinallyofsaid jaws, thesaidparts being so arrangedthat" the large end of said member, forms a rigid support for the operative ends-ofgsaid jaws when the latter'are in closed'posit'ion, and y said member beingprovided at itssmallerend with means for connecting a su'pportin strap thereto so that apull transmitted therethrough will draw said member through said stirrup to close *sa-id' jaws, and a the weightor pull ofthe material gripped by said jaws will increase the gripoffsaid jaws, 'substarnti'ally'as described. a
